–Different forging parts, require
different striking energy and combat force proportional to the square of the
rotational speed of the flywheel energy storage, a 5% rate fluctuations, will
generate 10% of the energy change. 1% of the energy of accuracy, speed
fluctuation to be less than 0.5%

③.Forming again
after hitting

–For some special parts, such as the low
plasticity alloy steel, non-ferrous metals, after blow molding, in order to
facilitate the metal recrystallization, the need for forming member and then
apply some pressure, when the motor speed is zero, you need to apply a
controllable motor torque

④.High efficiency ,automatic

–Meet the technological premise, in the
shortest possible time to complete a cycle, improve production efficiency, the
entire process automatic control
